The engines in Pimentel Phase 3 are almost twice as large as those installed in earlier phases. The complete Wärtsilä 18V46 diesel generating set is 18 metres long, five metres wide and has a height of six metres measured from the underside of the baseframe. The total weight is 358 tonnes.Transportation was therefore a major challenge.
Phases 1 and 2 have been operating non-stop since they started up, at least 8000 running hours each year. High efficiency means less fuel is used, making plant operation more profitable for the owner – an especially important factor in a baseload plant where fuel represents the highest cost component over the plant lifecycle.
